Abstract
The design of the power plant for the calculation of the thermal system and flow part of the pipeline design, to the maximum continuous evaporation of 2027t / h boiler and a unit capacity of 600MW steam turbine initial data through the principle of the determination of the thermal system And calculation, calculation and mapping of combustion systems, the determination of comprehensive thermal system and the design of pipelines. The choice of feasible solutions from the actual project, taking into account the safe and reliable, economical use, energy conservation, environmental protection, construction policy, while the operation is stable and reliable, the technology is mature and so on, comprehensive comparison to determine.
The design is mainly on the whole plant thermal calculation and calculation of the pipeline flow part of the pipeline and the choice of the same time to check the relevant soda water flow, intake capacity, power generation. According to the principle calculation results, the relevant basic dimensions are calculated according to the basic dimensions, and the relevant standard pipelines are selected according to the relevant standard hot pipe selection manual. The relevant pipelines are checked and checked to correct the selected pipeline model and optimize the power plant heat system.
And finally obtained the preliminary design of the power plant to determine the relevant system, come to a higher economy, the construction value of the power plant construction program.
Key words: thermal system; thermal economy; pipeline flow part
